Everyone has ups and downs. Sometimes you might feel a bit low, for lots of different reasons. People may say that they are feeling depressed when they are feeling down, but this does not always mean that they have depression.
Depression is a long lasting low mood disorder. It affects your ability to do everyday things, feel pleasure or take interest in activities.
Doctors might describe depression as 'mild', 'moderate' or 'severe'. Your doctor may offer you different treatments depending on how they describe it.
Depression can affect people of any age, including children. It is one of the most common mental illnesses. The number of people who have depression may be higher than this because not everyone with depression goes to their GP.
The NHS recommends that you should see your GP if you experience the symptoms of depression for most of the day and every day for over 2 weeks.
Doctors make decisions about diagnosis based on guidelines. One guideline used by NHS doctors is the International Classification of Diseases (ICD-10).
When you see a doctor they will look for the symptoms that are set out in the ICD-10 guidance. You do not have to have all of these to be diagnosed with depression. You might have just a few of them.
Your doctor should also ask about any possible causes of depression. They may also do some tests to check if you have any physical problems which might cause symptoms of depression such as an under-active thyroid.
There is no single cause of depression. Different things may cause depression for different people.
Some studies suggest that your genetics can play a part in developing depression. For example, one study found that particular genes may play a key role in developing recurrent depression. However, studies into the genetics of depression are at an early stage.
Researchers have also looked at whether having parents or other family members with depression can increase your chances of developing the condition. For example, some studies have looked into the effects having a mother with postpartum depression can have on children as they grow up.
Stressful events, such as problems at home or work, a relationship ending or financial issues may also make it more likely to experience depression.
Changes in your hormones and chemicals in your body may cause depressive symptoms.
For example, at some point many women might find their mood is affected in the weeks before their period, called pre-menstrual syndrome (PMS). Some women may struggle with premenstrual dysphoric disorder (PMDD) which has a lot of psychological symptoms similar to depression.
Having problems with your thyroid or having low levels of Vitamin B12 may also be linked to experiencing symptoms of depression.
Some studies have shown that not exercising, being under or overweight and having fewer social relationships can increase the risk of experiencing depressive symptoms.
Both legal and illegal drugs might affect your mental health. If you take prescribed medications, it is important to make sure you take them in the way your doctor suggests.
Some people will drink alcohol as a way to relieve anxiety or depression. However, the evidence suggests that if you drink regularly or misuse alcohol you are at a greater risk of developing depression.
Depression can come with other mental or physical health conditions such as such as diabetes or cancer. These conditions can make you feel low or may be a trigger for depression.
Some people with brain injuries and dementia may also have changes in their moods.
You might have heard a number of terms used to describe depression. Here are the most common forms of depression.
Clinical depression is a common term, but it is not a formal diagnosis. People sometimes say ‘clinical diagnosis’ to just mean they have been diagnosed by a doctor.
Your doctor might say that you are going through a 'depressive episode'. This is the formal name that doctors give depression when they make a diagnosis. They may say that you are going through a 'mild', 'moderate' or 'severe' episode.
Recurrent depressive disorder
If you have had repeated episodes of depression, your doctor might say that you have recurrent depressive disorder. They may say that your current episode is 'mild', 'moderate' or 'severe'.
If your doctor thinks that your episode of depression was caused by particular stressful events in your life, they may say that it is reactive. For example, divorce, job or money worries. This is sometimes separated from an adjustment disorder, where you may struggle with some symptoms of depression because of adapting to a major change in your life, such as separation from people, retirement or migrating to a new area.
Severe depressive episode with psychotic symptoms
If you are going through a severe episode of depression, you may get hallucinations or delusions. A hallucination means you might hear, see, smell, taste or feel things that aren’t real. A delusion means that you might believe things that don’t match reality. These symptoms are called psychosis.
Your doctor might diagnose you with dysthymia if you have felt low for several years, but the symptoms are not severe enough, or the episodes are not long enough for a doctor to diagnose recurrent depressive disorder.
Your doctor might diagnose cyclothymia if you struggle with persistently unstable moods. You might have several periods of depression and periods of mild elation. These periods of depression or elation are not severe enough or long enough to diagnose recurrent depression or bipolar disorder. Cyclothymia is more commonly associated with bipolar disorder than depression.
Post-natal depression refers to episodes of depression after childbirth. It is a common illness which affects more than 1 in 10 women within 1 year of having a baby. You may get symptoms that are similar to those in other types of depression.

Seasonal affective disorder (SAD)
This type of depression affects you at the same time of year, usually in the winter., The symptoms are similar to depression, but some people find they sleep more rather than less, and crave carbohydrates like chocolate, cakes and bread.
Manic depression is the old name for bipolar disorder. It is a different illness to depression. People with this illness have highs (mania) and lows (depression).
The first step to getting treatment is to see your GP. If your GP thinks you have depression, they will talk to you about the treatments they can offer.
Talking therapy is available on the NHS, from private healthcare providers and sometimes from charities. You will meet a trained therapist for a fixed number of sessions. Sometimes this will be with a group of people with depression.
There are different types of talking therapy that you might be offered. These include:,
The type of therapy you are offered will depend on the cause of your symptoms and their severity. Therapies may also have different levels based on how long or intense the treatment is.
Computerised cognitive behavioural therapy (cCBT)
Computerised cognitive behavioural therapy (cCBT) is one way of treating mild to moderate depression. You learn CBT techniques online using a computer. You will go through the same type of session as you would if you were with a therapist. It can be helpful after you have finished talking therapies to stop your symptoms coming back.
'Beating the Blues' is one of the cCBT programmes you can get. They are free but you need to talk to your GP about it.
Your doctor might offer you an antidepressant. You may need to try different types before you find one that works for you. If you do not want to take antidepressants, tell your doctor and you can discuss other options.
Antidepressants can have side effects and can affect other medicines you are taking. Your doctor will check if you have physical health conditions or if you take other medication.
It is important to talk to your doctor before you stop taking medication, because stopping suddenly can cause problems.
Regular exercise can help with your mood if you struggle with depression. Some GP surgeries will put you in touch with local exercise schemes. This is sometimes called ‘exercise on prescription’ and can give you access to free or reduced cost programmes.
Electroconvulsive therapy (ECT)
Electroconvulsive therapy (ECT) is a procedure sometimes used to treat severe depression. In this treatment, an electrical current is briefly passed through your brain while you are under general anaesthetic. This means you are not awake during the procedure. You should only have ECT if you have severe depression, it is life-threatening and treatment is needed as soon as possible. Or you may be given ECT if no other treatments have worked.
Transcranial direct current stimulation (tDCS)
This treatment involves using a small battery-operated machine to pass a low current through your brain to stimulate activity. You are awake during the procedure, with daily sessions for several weeks. NICE state that there is not a lot of good evidence for how tDCS works for depression, but there are no major safety concerns.
Repetitive transcranial magnetic stimulation (rTMS)
TMS uses electromagnetic coils to deliver pulses of magnetic energy to specific parts of your brain. This stimulates the brain and may help to reduce depression and anxiety. You are awake during the procedure and can leave hospital the same day. If this is offered, you may have daily sessions for several weeks. NICE have examined rTMS and found that it is safe and effective enough to be offered on the NHS.
Complementary therapies are treatments which are not part of mainstream medical care. They can include aromatherapy, herbal remedies, acupuncture, massage, meditation and yoga. These treatments may help improve your emotional wellbeing and may help with side effects.

A second opinion means that you would like a different doctor to give their opinion about what treatment you should have. You can also ask for a second opinion if you disagree with your diagnosis.
You don’t have a right to a second opinion. But your doctor should listen to your reason for wanting a second opinion.
